Current Profile at Various Startup Conditions
The diagrams below show the current profile for various startup conditions of the Propeller chip dependent upon the presence
of an EEPROM and PC.

Boot Sequence Current Profile for
no PC and no EEPROM (P31
held low and P29 not connected
(same as held low)).
Figure 8
Boot Sequence Current Profile for
PC (connected but idle) and no
EEPROM. (P31 held high and
P29 not connected).
